Statement on 9/11:
"In K. A. Seffen's paper, 'Progressive Collapse of the World Trade Centre',
the harbingers of nonsense are clearly visible. Seffen wrote: "It is also
clear that both collapse modes were progressive, as indicated by film footage:
there was the sound of each successive impact of floor upon floor and a
matching sequence of lateral ejection of debris." Yes, indeed, there were
sounds of each successive impact. But there were also sounds of explosions
and there are other important factors (for instance unusually melted steel,
angularly cut beams, insufficient temperature to melt steel, and so on).
The author seems to not care about these factors. Why? Because taking them
into account would force him to choose a different model and he is either
not willing or not able to do so. See my
analysis.
